If sensor has been replaced with oem part then next step is to have resistance tests done on wiring going to sensor...There are two wires that need to be tested...wiring should be under 5 ohms if not replace wiring/connector as needed...If you have any exhaust leaks that can also cause this code. Here are troubleshooting instructions from manual. Let me know if you have questions, thanks.

I have clean the connector with contact cleaner be for I install the sensor. I used electricun clener on the plug...
That is fine but you still need to check connecotr/pin condition then also do a resistance test on wires to make sure there are no shorts or broken wires. Let me know if you have questions, thanks.
